TY - CONF A1 - Krankenhagen, Rainer T1 - Basics of active thermography applied to CFRP and GFRP N2 - Starting with some examples from the VITCEA project, which gives the framework of the training course, the physical basis of active thermography is demonstrated. It consists of the physical phenomena heat conduction and thermal radiation. The contrast mechanism is explained by means of a simple 1-dimensional approach. This leads to the concept of thermal thickness which is essential for active thermography. Later, the influence of the surface properties reflectivity and emissivity is considered more in detail.
